Nl IETALLIC RAILROAD-Tl@ SPECIFICATION forming part of Letters PatentNo. 662,841, dated November 2'?, 190D.

Application iiled May 28, 1900. Serial No. 18,310. (No model.)

To a/ZZ whom, t may concern/x Be it known that L JACOB S. WARLEY, acitizen of the United States, residing at Pottstown, in the county ofMontgomery and State of Pennsylvania, have invented new and usefulImprovements in Metallic Railroad-Ties, of which the following is aspecification.

In the accompanying drawings, Figure lis a side view of the tie, partlyinsect-ion, showing the construction. Fig. 2 is a section of the middleportion. Fig. 3 is a plan view. Fig. 4 is a plan view ofthe sill-platedetached. Fig. 5 is a section of the sill-plate detached. Fig. 6 is aplan and side view of the end portion of the tie. Fig. 7 is a view ofthe end of the tie and a sill-plate in process of attachment thereto.

The invention has relation to metallic sills or ties for railroads; andit consists in the novel construction and combinations of parts, ashereinafter set forth.

In the annexed drawings the letter A designates the transverse tie,consisting of heavy sheet or plate metal, or it may be cast in form.This metallic tie consists of the middle portion B, which is flanged inform and terminates at each end in ilat extensions C, formed withdepressed seats D to receive the rail-base. Said middle portion B of thetieplate lies below the planes of the flat end portions thereof inposition to have its inclined sides ballasted in the road-bed. The underside of the extension C is usually formed with a pivotal depression orprojection c to engage a center bearing f of the sill-plate G. Thesill-plate is formed with a plain surface having a depression h in itsmiddle portion of proper size to receive the bottoms of the seats D ofthe tie extensions and wide enough to allow of some turning of saidseats therein. When the seat D is in place in the depression, thebearing of the seat and the plain surface of the sill-plate are flush,so that the rail-base will have a rm bearing thereon. The sillplate isprovided with. the lateral flanges J, which extend downward and somewhatontward obliqnely, as indicated in the drawings, being designed toengage ballast in a iirm manner and to be packed so that the sillplate,and consequently the tie, will be securely anchored and braced inposition. This effect is aided by the form of the flanged middle portionof the tie. The sill-plate is provided with the raised hook-lugs Ic,diametrically opposite each otherand projecting, as shown, from theplain surface of the sillplate, being directed toward each other onopposite sides of the rail-seat in order to engage the rail when thesill-plate is turned thereunder on the pivot of the tie extension. Whenthe rail-base is engaged by the lugs la, the parts are securelyconnected together,the railbase holding the tie extension in thedepression of the sill-plate. An automatic lock is provided, usually inthe form of a third lug m, which when the sill-plate is turned to properposition escapes from under the tie extension and engages the edge ofthe latter, preventing any turning of the sill-plate in the reversedirection. This lug can be forced down when it is desired to unlock theconnection in order to disengage the parts.

This tie is designed-to serve an excellent purpose, as it is light andstrong and is locked automatically in and by the ballasting. It iseasily constructed, as the lugs of the sill portion may be struck up,and made in this manner it will consist of but three portions-thetransverse tie portion and the two sill-plates.

Having described this invention, what I claim, and desire to secure byLetters Patent,

l. In a railroad-tie, the combination of the sheet-metal sill-plates,having depressions in their upper surfaces, of the sheet-metal tieplateshaving iiat end portions, provided with depressed rail-seats engagingsuch sill-plate depressions to provide an uninterrupted bearing-surfacefor the rails, said sill-plates having diagonally-located stop-lugs, anda locking-lug, for the rails, together with means for providing apivotal connection of sill and tie plates, substantially as specified.

2. In a railroad-tie, the combination of the i sheet-metal sill-plateshaving depressions in their upper surfaces, and a central bearing insaid depression, of the sheet-metal tie-plates having iiat end portionsprovided with depressed rail-seats engaging said sill depressions, andhaving a pivotal projection engag- IOO In testimony whereof I afx mysignature in presence of two witnesses.
